Аннотация: In this talk, we classify linear (as well as some special nonlinear) scalar diff erential operators of order Thus, at first, we consider the classical problem of Gl-invariants of After all, we apply the Depending on available time, we show how to extend all these results to some classes of nonlinear operators.
